- DVD Player Service Precautions

1.Never adjust the LD VR in the pickup unit to protect the pickup from electrical damages.

2.For pickup unit(service)(CXX1530) handling, please refer to"Disassembly"(see page 109).

During replacement, handling precautions shall be taken to prevent an electrostatic discharge(set the short switch

of the pickup unit to the SHORT side).

3.During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged.

4.Please adjusting the skew after changing the pickup unit(see page 83).

1. SAFETY INFORMATION

1.1 UC

CAUTION

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm.

Health & Safety Code Section 25249.6 - Proposition 65

1.2 EW

1. Safety Precautions for those who Service this Unit.

•Follow the adjustment steps (see pages 80 through 100)in the service manual when servicing this unit. When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.

Caution:

1.During repair or tests, minimum distance of 13cm from the focus lens must be kept.

2.During repair or tests, do not view laser beam for 10 seconds or longer.

2.The triangular label is attached to the mechanism unit frame.

LASER PRODUCT

On the bottom of the player.

CAUTION : VISIBLE AND INVISIBLE LASER RADIATION WHEN OPEN.

AVOID EXPOSURE TO BEAM.

WARNING!

The AEL (accessible emission level )of the laser power output is less than CLASS 1 but the laser component is capable of emitting radiation exceeding the limit for CLASS 1.

A specially instructed person should do servicing operation of the apparatus.

Laser diode characteristics

Wave length:

DVD:640~660nm

CD:770~810nm

Maximum output:2.44mw(Emitting period :9sec.)

DVD:743mw(Emitting period : unlimited)

Additionla Laser Caution

Transistors Q1104 and Q1108 in PCB drive the laser diodes for DVD and CD respectively. When Q1104 or Q1108 is shorted between their terminals,

the laser diodes for DVD or CD will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam.
